This script varies the steering speed depending on the speed you are driving, and it rotates the camera to match the steering angle and direction.
Shift-Left limits throttle, cruise control and maximum rounds per minute to 75%. With Shift-right and the cursor keys you can peek in the corresponding direction.
If you press Ctrl left together with W then the driving direction snaps to fixed directions.

All functions are switchable with the following default key combinations:
[Ctrl Left + C]: Settings
[Ctrl Left + W]: Snap Angle (continue)
[Alt Left + W]: Snap Angle (restart)
[Shift Left]: Throttle limiter / reduced cruise control speed
[Shift Right + Cursor]: look forward, backwards, left right
[Space]: Change direction (aka shuttle control)
[[]: Gear up
[‚]: Gear down
[]]: Range up
[#]: Range down
[;]: Neutral and handbrake
